ERV, though it does not specifically say this anywhere I could find, is short for endogenous retroviruses. Written by Abbie Smith, ERV pretty consistently focuses on issues relating to endogenous retroviruses, HIV and other retroviruses or the politics of issues such as vaccination. Recent posts include Building a better GMO virus for Hemophilia B, Long-term effects of CIA ‘vaccination’ ruse to find Osama bin Laden and CERVs! Crocodile ERVs (not chimpanzee!). Not a lot about the built environment there but if you want to keep up with information about retroviruses it is a good place to lool.
